The carrier aims to deploy the SSJ100 to San Antonio no later than September, says Interjet chief executive Jose Luis Garza. Interjet currently operates AirbusA320s on its flights to San Antonio from Mexico, and will substitute the A320 with the SSJ100 on some routes as the peak travel season slows down.

Interjet will likely deploy the SSJ100 on San Antonio-bound flights from Mexico City and Toluca, says Garza.

"The high season ends around mid-August," Garza says. "As soon as it finishes, we will switch to the SSJ100." Interjet's SSJ100s are configured with 93 seats, and the airline deploys them on thinner routes that do not have enough demand to fill an A320.

Interjet had previously hinted that it would operate the SSJ100 on the first US-bound flights to destinations in Texas, but has not until now specified which cities will receive the service.

The carrier operates eight SSJ100s on domestic flights currently, and will receive 12 more of the type this year and in 2015.

Interjet is also looking at deploying the SSJ100 on its flights to Central and South America eventually, says Garza. "It will be gradual," he says. Outside of Mexico and the USA, Interjet operates to Bogota, San Jose in Costa Rica, Havana, and Guatemala City.
